Help needed with Peugeot speedfight 50cc ac lighting rectifier

I have just got a old speedfight 50 ac 1999 to do up for my son .I have rebuilt everything just about everything is new .I have come to the wiring and again repaired as necessary. But on the speedfights it has a lighting resistor that connects to a pink wire .the harness on mine is different I think it is off a 100 not sure. But there is no pink wire or green for either of the rectifier that mount on the front bracket behind the head lamp

 

You tube,Mark savage.over 100 vids on the speedys. May help you.

 

Thank you. I have looked through alot but nothing on the lighting resistor
